The connection to host on port 465 failed.
I am suddenly getting no outgoing mail on my Mac Mail application through my domain account. The error message is "The connection to host (**Domain Mail Server**) on port 465 failed." My domain host service provider went through all SMTP servers and ports that should work and have worked in the past. ATT first level tech service was of no help and sent me to the pay Connect Tech service. I had a similar problem a could of months ago with the incoming servers and it turned out to be an ATT problem. I think it is again, so don't want to pay and don't think I should. I just want to verify the correct settings. Why should that be a pay service?
Isn't port 465 correct? Isn't SSL enabled best?
